Tb' al@ ,whom a may-mam' 13e 1t knownthat I, HERMAN QQWOLFF, a citizenof the United States, and resident of Syracuse,- in,l the'. countyA ofLOnondaga, in the State of New York,v have-invented new and vusefulImprovements in Sash Locks and 'Il ightenera o which the following,taken in connection wlth the accompanying drawings,

isha full, clear, and exact description.

for securely locking the window-sash `in' its closed posltion andsustaining it at 'different elevations in its open position and also.in`

means for tightening thesash in the 'Windoweasing so as to prevent thesash vfrom rattling and exclude air from the joints between the sash anditsI bearings inthe casings,.-all `as hereinafter explained and claimed.

In'the accompanying drawings Figure 1 f is' a vertical section throughthe stile of the sash and the inner jamb, or so-called window stopshowing the invention a plied thereto; Figs-2 and 3 show enlargedliorizontal secon the lines 'anenlarged'fragmentary r'ontlview showingthe devices for c unlocking and raising the sash;- .F :5 is a transverseksection on the line Figli; Figf illustrates 'some of"` thefdetailsofthe'invention; Fig. 'Z is a detachedview of the 'dog engaged to supportl*the sash in its open position; Fig. 8 is a vertical sectional view ofa modiiication of my invention; Figs. Qfand' 10 are detail views ofsad'mOdcatiOn; and Fig. 11 is a transverse section of Fig; 10.

'-In' the'said drawings-S- denotes one of the stiles 'of the sash, A-is,` the inner.

jamb; usually called window-stop, which is' attached-to the windowcasing to retain the sash therein. -`B-' is the outer jamb, which in'twosashed lwindows is `designated the dividing strip. The inner jamb f-A-is formed withv a lverticallv elon ated recess .-A1 in theedge'adjacent'to tie sashrand in the said recess isa series of suitablecatchplates '-a-y-dfmetal rigidly' attac catedat #wn-alteh and formedwithjshort upwardl 'projecting' tongues -fa1 and bearing aces @2;between said tongues and main or central portions 'ofthe metal strips..

referably composed of The recess-Alfwiththe series of catoli-`plates'terminates at a suitable distance from the top ofthe sashto'cause the ledgeof the jamb -A- to present a continuouseven lsash frombeing raised to its open ed to said jamb, as indilaround the pivot ofthe cam and track -`Z1-- above the recess -Alfor the purpose hereinafterInade apparent.

Theedge of the stile S adjacent to the j amb -A- is rovided with arecess -oextending lengt wise ofthe stile, and in the said recess isrigidly secured .a metal bar -.c1- which is preferably L-'sha ed incrosssection and disposed with its wa l Hush with l the front and sideof the stile. Thls'mvention consists 1n improved means r To the lowerend portion of the bar.c' is .pivoted the. sash-locking dog -d. the

free end of which is hook-shaped to engage the tongue .-0 ,.2- of one ofthe catchplates --aas shown in Fig. 7 and thereby sustain the' sash atthe desired elevated open position. The free end of the dog is also'formed 'with a transverse shoulder -dlwhich is shaped to engage thelowermostbearing-face -a2 as shown in Fig. 1 so as to prevent theosition.

lThe pivoted end of the dog is e ongated transversely and `under thesaid end is a lever e which is firmly 'attached to a horizontal shaft -fpivoted to the wall -cof the bar -c-' and'extending into a channel-fformedin the bottom rail C- of the sash (see Fig. 4). The'in'ner endof said shaft is pivo'ted to the saidfbottom-rail and has fastened to ita lever gby means of To the exteriorof t e bottom rail -C is fastened aplate -D- which has proj ectin from it a rigid thumb-piece -DL- disposeabove the lever p -K-g-f, which protrudes as shown in i s.` 4 and 5. Thesaid opening 4is suicien-tly ar e to receive in it a stopslioulder -gl-eormed on the lever -gland in position to contact with the upper edge ofthe opening .-hand leave the lever in a convenient'position to beoperated in unlocking the sash'.

which the dog can be thrown out of engagement with the catchlate a-.

-L- represents a cam which is pivoted to the upper end 'portion of thebar -c1- and disposed to bear on the even track #bw so as to ress thesash out-ward and tighten the joint getween the-exterior of the sash andin nerside of the outerjamb -B-. Said cani is actuated by an individualspring -i-, which may consist of' 'a spring wire coiled ressmg withoneend onsaid cam while bearing with theOppOsit'e end 4of the said wireon' the plate -j-T- Ol ass-shown' inFig. l-Ofof the drawings. When whichthe cam is pivotally mounted the spring il-'is employed and arranged inthe manner described I provide the dog -dwith an operating springl -i2-similar to the spring.,r -tlas shown in Fig. 11 of the drawings. Iprefer however to einploy a spiral spring -iin connection with a tube-cdepending 'from the pawl -I-- to which it is connected at a pointbetween the )ivots of t-he cani and the track -bonthe inner jainb -i- Asimilar tubo -rlis connected to the dog` --din the saine rela-- tiveposition as the tube -7t'- and extends upward from the dog as shown inFig. i. In

. the lower tube -r is fastened the lower r in the strap.

end ot a rod -Z-' as shown at *o* the upper end of which is slidablyinserted in the upper tube -k--- The spiral springI .--isurrounds thesaid rod and bears with its ends on the ends of the tubes. The springeris thus supported on the dog -cZ- and exerts its force on the cani -I-to press said urpo'se aforesaid. To prevent said cam rom marring'theinner )amb ---iduringT track, a spring supported on the-dit;y andforcing the cani to the track, and a strap actuated simultaneously withthe movement of the dog from its locking position and drawing the camfrom the track.

3. The combination with the easing and sash, of a series of catch-platesand an even track on the inner jainb, a sash-locking dog pivoted to thesash to engage the catchplates, a cani pivoted to the sash opposite theaforesaid track, tubes connected separately to the dog and cani atcorresponding,r sides from the pivots thereof, a rod attached to one ofsaid tubes and inserted slidably in the other tube, a spiral springsurrounding;T said rod and bearingr on the ends of the tubes, and alongitudinally movable strap eoniieett d at one end to the tube ot thecani and actuated b v the movement of the dog from its locking positionand drawing the t cani from the aforesaid track. cani outward aga-insttlie track Iifor the 4. The combination with the casing and 2 sash, ofcatch-plates attached to the inner the vert-ical movement of the sash toand I from its open and closed positions I employ a metal strap -twhichis connected at its upper end to the upper tube -r--, and connect thelower endof said strap to the inner -.-non said lever inserted into anaperture In operating the lever -eto throw .the dog -dtroni engagementwith. the catch-plate -a.-, the upper tube -c-- is drawn down and causedto draw the cani -I-- inward and free. from the track -Z-, 1n whichposition the cani reni-anis until the lever-eww is released to allow thedog fatto engage the catchnte -c In the modifie-ation illustrate( inFig'. S of the drawings, the strap -tis connected at its upper endto,tlie cani -I-.and at its lower end to the periphery of a spool-pattaclied tothe shaft. -f-f A short strap -rconnects the strap -t tothe dog -dso that the cam -I- is drawn out ot contact with` tlietracklisimultaneously with the thrust of the dog' -dfrom its en gagement withthe catch-plate -a-.

That I elaini as my invention is:

2. The combination with the easing; and sash, of a series ofatteli-platestmi even track on t-lie inner janib, a sash-locking' doppivot-ed to't'lie sash opposite thealoresaid faces between said tongues,and a sashloeking dog,r pivoted at one end to the sash and formed at itsfree end with a hook l'or engaging the said tongues and with a shoulderon the latter end for eiigagiiiel the bearing laces as set forth.

6. rl`he combination with the easingilr andl sash, ol a sash-loekin; rdogr pivoted to the sash and fornied'with an outwardly projectingshoulder on the pivoted end thereol', a` rock-shaft pivotallv supportedon the sash, and a two-arnried lever fastened to said roekslial't, onearm ol the lever being disposed to engage the al'oresaid shoulder', whenthe dotr in lockingr position, and the other artn operative forthrowingr the dotr ont ol' said position as setl'ol'tli.
